All required improvements shall be constructed in accordance with plans and standard specifications approved by the City Public Works and Safety Committee, City Engineer, Wisconsin Department of Natural Resources and Milwaukee Metropolitan Sewerage District, as may be appropriate. Such plans and standard specifications shall be submitted, reviewed and approved in accordance with § 392-69 of this chapter.
A. 
The improving of a dedicated roadway to City specifications must follow the following guidelines: All land divisions which create new public right-of-way shall be required to improve, within said right-of-way, a public road to City of Muskego specifications and detail drawings. Should the road end with a permanent cul-de-sac, land must be dedicated per City standards and the road constructed to City of Muskego specifications. Should the road end with a future possible road extension, a temporary cul-de-sac may be constructed with a temporary easement; however, the size must be the same as a permanent cul-de-sac. City of Muskego stormwater management requirements must be met should the improvements add more than 1/2 of an acre of impervious surface. All roadway, grading, storm sewer, and stormwater plans must be reviewed by the City of Muskego as required by Municipal Code. The following requirements vary by the size of the parcels being divided:
(1) 
Should a land division create parcels with an average size of less than or equal to 40,000 square feet, the road shall be built to City specifications that include curb and gutter and storm sewer.
(2) 
Should a land division create parcels with an average size of greater than 40,000 square feet, the developer may choose to request a Public Works and Safety Committee decision regarding the type of improvements required. The only option Public Works and Safety Committee will consider other than curb and gutter section is ditch section construction per City of Muskego specifications. Should this option be permitted, the ditch sections shall be maintained by the developer initially and ultimately the homeowners' association. Furthermore, these restrictions outlining the responsibility for this maintenance shall be recorded in a developer's agreement approved the City's Common Council concurrent with the final land division document.
(3) 
Private driveways within newly created public right-of-way are not allowed under any circumstance.
B. 
Improvements to be extended to farthest limit of parcel or lot. Any and all improvements, streets, or utility services required by this chapter for the subdivision, certified survey map, or condominium plat shall be extended to the farthest limit of the parcel or lot as set forth on the plans and specifications approved by the City. If determined by the Plan Commission, based on the information of engineering staff, that a resulting development will cause increased effects on existing infrastructure, the cost of all reasonably necessary improvements on the exterior of a development, such as expanded roadways, intersections, and/or utility extensions, shall be paid by the developer/owner.
C. 
Improvements to be extended to farthest affected area. Any and all improvements, streets, or utility services required by this chapter for the subdivision, certified survey map, or condominium plat shall be extended to the farthest affected area. If determined by the Public Works and Safety Committee or Plan Commission, based on the information of engineering staff, that a resulting development will cause increased effects on infrastructure, the cost of all improvements on the exterior of a development, such as expanded roadways, intersections, and/or utility extensions, shall be paid by the developer/owner.

The subdivider shall grade the development pads and full width of the right-of-way of all streets proposed to be dedicated in accordance with plans and standard specifications approved by the City Public Works and Safety Committee and any agency having jurisdiction, including the Wisconsin Department of Natural Resources, upon the recommendation of the City Engineer. The subdivider shall grade the roadbeds in the street rights-of-way to subgrade.
C. 
Where electric and communication facilities are to be installed underground, the utility easements shall be graded to within six inches of final grade by the subdivider prior to the installation of such facilities, and earth fill, piles or mounds of dirt or construction materials shall not be stored on such easement areas.
After the installation of all utility and stormwater drainage improvements, the subdivider shall surface all roadways in streets proposed to be dedicated to the widths prescribed by these regulations and the adopted Comprehensive Plan or adopted plan components. Such surfacing shall be done in accordance with plans and standard specifications approved by the City Public Works and Safety Committee, upon the recommendation of the City Engineer, and adopted by the Common Council or its authorized agents. The second lift of asphalt shall be installed in accordance with policies established from time to time by the Public Works and Safety Committee.
The Common Council may require the subdivider to construct concrete curb and gutters in accordance with plans and standard specifications approved by the City Public Works and Safety Committee, upon the recommendation of the City Engineer, and adopted by the Common Council or its authorized agents. Mountable curbs shall generally be constructed.
A. 
The Plan Commission and Common Council may require the subdivider to construct a concrete sidewalk or asphalt off-road path on one side of all frontage streets and on one or both sides of all other streets within the subdivision. The construction of all sidewalks and paths shall be in accordance with plans and standard specifications adopted by the Common Council.
B. 
Wider than standard sidewalks or paths may be required by the Plan Commission and Common Council in the vicinity of schools, commercial areas and other places of public assemblage where the potential pedestrian density may warrant, and the Council may require the construction of sidewalks in locations other than required under the preceding provisions of this chapter if such walks are necessary, in its opinion, for safe and adequate pedestrian circulation.

In addition, the subdivider shall pay to the City a sanitary sewer trunk line connection fee based on the added cost of installing larger sewers in the total tributary drainage area which shall be prorated in proportion to the ratio which the total area of the proposed plat is to the total drainage area to be served by such larger sewers.

Associated equipment and facilities which are pertinent to underground electric and communications systems, including but not limited to substations, pad-mounted transformers, pad-mounted sectionalizing switches and pedestal-mounted terminal boxes, may be located above ground. Any landscape screening plan required for such aboveground equipment shall be submitted to the affected utilities for approval.
